Hmmm....
Ever tried to push the tape loose, using the canopy? Ever calculated the air pressure download on the forward part (base) of the canopy at 150mph? (I haven't, but I am curious...)
On making the canopy depart: Most evidence indicates that the rear of the tipup canopy floats a few inches up when unlatched in flight. Anyone looked at how far up it would have to go to allow the hinge arms to clear the forward skin, if it *isn't* notched? There's obvious risk of getting the canopy in your face, but I suspect that risk exists, anyway.
